Vect can you try to ear a flac file or wav file in 88,2 KHz and 24 bits and see if you can fell any diference between that and the same file in 44,1 KHz 16 bits?

There shouldn't really be an audible difference between the two if they're of the same master.

As for the external amp comment, often times an external headphone amplifier is designed to meet certain specifications that an on-board amp in a portable media player doesn't. i.e. an on-board amp may not be as clean as an external one

Has anyone compared the F880 to the FiiO X3?Edited by miceblue - 12/15/13 at 4:15am
